Question

15.4.1 another big step backwards on my system OSX

Without OpenCL support, and relying on Metal or Software Only rendering, I get no real-time playback whatsoever with .mxf clips with one instance of Red Giant Colorista applied - even at quarter resolution. A massive number of frames are being dropped, with only occasional bursts of real-time performance.

This is with 4K source footage in an HD Sequence, both at the same frame rate of 23.976.

This renders this version of Pr completely unusable to me. For reference, Pr 14.9 is still working like a champ, which I infer is because of the OpenCL support that Adobe chose to discontinue for Pr 2021.

I have a powerful MacPro7,1. System Compatibility Report finds "No Conflicts to Report."

MacPro7,1 - 2.7 GHz 24-Core Intel Xeon W - 256G RAM - AMD Radeon Pro Vega II 32 GB

ATTO R680 PCIe SAS SCSI RAID6 (8 drives)

OSX 10.15.7

I wonder if anybody with a similar computer gets acceptable results on Big Sur, or has any other idea for the reason for my thread title.

Hardware or GPU

Jim, I'm trying to create something to simulate your workflow, and I have a question for you that I don't think has been asked yet:

Are there certain parts of your sequence that drop frames, while other segments play back without dropping frames? If so, I'd be curious to know what all is happening in the parts of the sequence that reliably drop frames.

I've got some 4k media that I'm scaling to fit a 1080 sequence (that's correct, yes?). Some MXF Op1a, some ProRes4444, some PNG stills with alpha, and I'm applying Colorista (V). I also have a 1080 source that I've stabilized in its own sequence. Any other variables I need to throw in?

Hi, DS. Yes, certain sections play without frames dropping, such as when there's one instance of Colorista IV. But, as soon as the CTI hits a spot with a PNG super, or an additional effect, it starts dropping frames and keeps dropping them. Once the Dropped Frame light turns yellow, it stays yellow, unless I hit the spacebar twice. Then, depending on what the section I stopped on has going on, it may stay green for a few seconds before turning yellow again.

I've been given mostly 4K .mxf footage recently, shot at 23.976 that I'm using in 23.976 HD Sequences. But, I'm seeing the same poor Metal performance with 4K ProRes 422 captured on an Atomos Ninja, and that codec is eaven easier on the GPU than .mxf, IINM.

What kind of computer are you using?

Thanks for getting back to me, Jim. These tips may be helpful in getting a repro here, and I'll keep you posted. I've got a 2017 model iMacPro, 3.2GHz, 8-core Xeon, with a Vega64 (16GB). I suspect it's especially relevant that once you hit a bottleneck, the frames keep dropping and don't recover. I'll spend some time nosing around in that direction.

I'll say this: both on the Imac system and on Windows, the use of standard effects (not to mention third-party plugins) is no good for a professional video editing program. Let those who are reading now experience the application of various kinds of effects to their project on their own machines. Am I interested in hearing the opinion of others??? Or is everything perfect for everyone??? I won't believe it. I have one opinion for the majority of users, so this is that they simply do not apply them to their projects, so there is no response.

I had some time to do more experimenting. I trashed my 15.x prefs, reset the plug-in cache, opened a 14.9 project, deleted all the third party effects from my Sequence, and saw SOME improvement in playback. It's still periodically dropping frames.

So, I applied Colorista IV to some clips, and to my surprise, it played back SOME of the clip in real-time, but eventually started dropping frames.

I have iStat Menus installed, and can see how my CPU (24 cores) and GPU are being utilized. On starting playback, I occassionally see ALL my CPU cores being pegged for a few seconds, then slowly reducing to just a few cores working moderately, which is something I hardly ever see in any app. I see my GPU meter going to about 60%, then slowly reducing. This is completely different from what I see in Pr 14.9.

I wrote to RedGiant about this, Kevin, and I don't expect a reply for days. Their support is usually marginal at best, and non-existent on weekends.

Jim,

I've the full RG Universe ... and had the RG app manager stop taking my logon. Tried the Maxon app, wouldn't take my logon. Their site logged me in instantly but the app manager wouldn't.

Contacted RG/Maxon support and got an email back in only three hours. Which is a lot better than I'd have before. Basically, told me to uninstall the RG manager and go to the new Maxon one, try that. Which eventually worked.

But I even had followups from them! So maybe Maxon taking over RG might get us better support. Michael Szalapski (known as the ACP Szalam on the Ae board) is now with Maxon, and is a very good user-focused person. I hope that's a good sign.

And it's really a puzzler watching how PrPro and Ae play out on different systems. I can't always fit any logic to it. Some major machines choke, some fly. Some weak systems fly, many choke. What the ... ?

Just puzzling.

I would note that the removal of OpenCL support on the Macs is due to direct instruction from Apple. Sadly.

I concluded that the premiere itself works normally. But when you throw on the effects, THAT'S IT. You can finish and do no more. Why don't they eliminate it????

Baffy,

Are you also in a situation where you have only Metal GPU acceleration too? Can you share your experience too?

Thanks,
Kevin

Update: I just opened two older projects in which source footage and Sequence are 29.97, and getting better real-time performance. One had ProRes sources, and another had .mxf.

I had tried several other projects with 23.976 sources (.mxf) and sequences, and got many many dropped frames on all of them.
